INSTRUCTION DESCRIPTION OF THE INVENTION (1) Field of the Invention The present invention relates to a liquid crystal display device, and more particularly to a liquid crystal display device having a reflector, a reflector, and a method for fabricating the same. Technical Description The liquid crystal display device is decomposed into a liquid crystal panel, a driving circuit, and a light source. The liquid crystal system is sealed in the liquid crystal panel, and the driving circuit causes the liquid crystal panel to locally change the transparency of the liquid crystal. The light is radiated from the light source through the liquid crystal panel, and the transmitted light generates an image on the liquid crystal panel. Therefore, the light source is an important component on the liquid crystal display device. The light source includes: a lamp tube; an optical guide plate; a reflector; and a power supply cable. The optical guide sheet is bonded to the liquid crystal panel, and the tube is opposed to the side surface of the optical guide sheet. The lamp is surrounded by a reflector. When electricity is supplied to the lamp through the power supply cable, light is radiated from the light source. The light is partially incident on the side surface of the optical guide sheet. Most of the remaining light is radiated towards the reflector and is reflected from the reflector towards the optical guide. The incident light propagates through the optical guide, and the liquid crystal panel, i.e., the pixel array, is uniformly illuminated by the optical guide. Fig. 1 shows a standard example of a conventional liquid crystal display device. The liquid crystal display device generally includes a light source 1, a liquid crystal panel 5, and a circuit board 6. The driving circuit is coupled to the circuit board 6, and the circuit board 6 is attached to the side surface of the liquid crystal panel 5. The light source 1 is assembled with the liquid crystal panel 5, and the liquid crystal panel 5, the light source 1 and the 1288260, and the circuit board 6 of the invention (2) are housed in a suitable casing (not shown). The light source 1 comprises: a reflector 2; a power supply cable 3; an optical guide 4; and a lamp 1 〇. The optical guide plate 4 is as wide as the liquid crystal panel 5 and has a light output surface. The light output surface is opposed to the back surface of the liquid crystal panel, and the reflector is attached to the side portion of the optical guide plate 4. The reflector contains a reflective surface that defines a space with the side surfaces of the optical guide plate 4. The tube 10 has a cylindrical shape and is provided in the space. The power supply cable 3 is connected to the bulb 10, and power is supplied to the bulb 10 through the power supply cable 3. The bulb 10 has a cylindrical shape and is formed with electrodes on both end surfaces of the bulb 1 。. The reflector 2 is as long as the tube 1 ’ (see Fig. 2) and has a passage shape. The upper side / ~ (the side of the side of the ox plate protrudes from the upper/lower end of the vertical flat portion 2a. The tube 1 〇 ' falls between the upper flat portion and the lower flat portion, and the electrodes are exposed therebetween. The two ends of the space are defined. The power supply cable 3 comprises: a high voltage line 3 a; a low voltage line 3 b ; and a round cable 32. Although not shown in the first to third figures, the high voltage line 3a and the low voltage line 3b is connected to a power source. The high voltage line 3a is directly connected to the electrode, and the low voltage line 3b is connected to the other electrode through the round cable 32. The round cable 32 is as long as the reflector 2. And is provided on the vertical flat plate portion 2a. The circular cable 32 has a circular cross section, and its diameter falls within a range from 0.5 mm to 1. 〇 mm as shown in Fig. 3. -4- 1288260 V'Invention Description (3) The problem encountered by us is that the conventional light source occupies a very wide space. This is due to the fact that the circular cable 3 2 is used to connect the low voltage wire 3 b to the electrode of the lamp 10 . The round cable 3 2 itself occupies a very wide space and is in a round cable with An extra space is required between the components. I have a kind of early-type flat electricity. Figures 4 and 5 show another conventional light source 1. The conventional light source also includes: a reflector; And a power supply cable 32. The reflector and the lamp tube are similar to the reflectors and tubes in the conventional light source as shown in Figures 1 to 3, and are labeled with the same symbols. The cable 32 comprises: a high voltage line 3a; a low voltage line, 3b; and an elastic flat cable 33. The high voltage line 3a and the low voltage line 3b are connected to a power source (not shown). The high voltage line 3a is directly connected to the lamp tube 10 On one of the electrodes, the low-voltage wire 3b is connected to the other electrode of the lamp tube 1 through the elastic flat cable 33. The elastic flat cable 33 is fixed to the reflector 2 by the adhesive compound 34. The vertical flat portion 2a has a thickness of 0.2 mm, and the thickness of the viscous compound 34 falls on the level of 0.1 mm. The total thickness falls on the level of 毫米. 3 mm. If so, the advantage of the elastic flat cable 33 is reduced to interconnect The space occupied by the cable. We have put a lot of effort into research and development on a lightweight LCD panel with a wide image-generating area. This technical goal is to reduce the area of the frame, that is, the area around its image. The peripheral area is achieved. The interconnecting cable 3 2/3 3 is positioned under the frame area, and accordingly has a non-negligible influence on its frame area. Although the elastic flat type 1288260 5, the invention description (4) The use of the cable 3 3 results in a relatively narrow frame area, and the total thickness on the meter level is too far from the target. A very thin interconnect structure is proposed in Japanese Unexamined Patent Publication No. 10-206847. Fig. 6 shows a conventional liquid crystal display device. The circuit board 6 is provided on one of the side portions, and the optical guide plate 4 is overlapped with the circuit board 6. The light source is provided on the optical side and also includes: reflector 2; lamp 1 〇; and 35. A reflector is defined by the reflector 2 and the optical guide plate 4 to be provided in the space. The power is supplied from the power source through the 35 to the lamp tube 1 . A voltage line (not shown), an indication, and an interconnect structure 36 form a power supply cable 36 that is deposited by depositing a thin conductive layer of the reflector by evaporation techniques. The thickness of the interconnect structure 36 is in the range of 0.0005 mm to 0.001 mm. The interconnect structure 36 is electrically conductive to reduce its frame surface anger over the interconnect structure 36 deposited by the evaporation technique. It is less likely to undergo disconnection, cracking, such disconnection, cracking, etc. after completion of the liquid crystal panel. And the peeling phenomenon is caused by thermal stress or other external force on the structure, and heat is also radiated from the tube 1 and the temperature of the thermal energy device. Thermal stress is generated between the reflector and the interconnect structure 36, and the very thin interconnect structure is rendered operative. However, what is dropped in the 0.3 mm publication is a power supply cable space in which the liquid crystal panel 5 and the liquid crystal panel guide 4 are exposed and the lamp tube: power supply cable low voltage line (not labeled 35. interconnection structure) The $ on the outer surface falls on the righteousness. However, it is easy to peel and peel off. The force is very thin and interconnected. Not only the light at the same time "increased the thermal expansion of the reflection 丨 can not withstand its shape 1288260. (5) Another inherent problem with the like interconnect structure 36 is its high manufacturing cost. The evaporation system is extremely expensive and its yield is small. The extremely thin interconnect structure is very expensive through the extremely expensive steaming system. It is deposited at a low yield. This results in extremely high manufacturing costs. SUMMARY OF THE INVENTION It is therefore an important object of the present invention to provide a reflector formed from a highly reliable conductive pattern. An important object of the present invention is also to provide a use. A method for manufacturing the reflector in an economical manner. Another important object of the present invention is to provide a liquid crystal display device equipped with the reflector. It is proposed to cure a layer having a conductive coating printed on a reflector to produce a conductive pattern.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A first sinus embodiment reflector with reference to Figures 7 and 8' for illuminating the light source 1 of the present invention includes: a reflector 2; a lamp tube 10; a power supply cable 38; and an optical guide plate 4 (See Figure 9). The lamp 10 is placed in an internal space defined in the reflector 2, and is supplied with power from the power source (not shown) through the power supply cable 38 to the lamp 10. When the lamp 1 启动 is activated, the lamp 1 〇 1288260 5, the invention (8) emits light 'and part of the light is reflected on the inner surface of the reflector 2 to be guided onto the optical guide plate 4. The reflector 2 has a passage shape and can be decomposed into: a vertical flat plate portion 2a; a relatively short upper flat plate portion projecting from the upper edge of the vertical flat plate portion 2a; and protruding from the lower edge of the vertical flat plate portion 2a Long lower flat section. The internal space is defined between the relatively short upper flat plate portion and the relatively long lower flat plate portion. The reflector 2 is formed of a thermoplastic resin such as polyethylene terephthalate resin. Polycarboxylate resin can also be used to form the reflector 2. These resins are all insulating materials and current cannot flow through them. A conductive pattern 31 is formed on the vertical flat plate portion 2a. The conductive pattern 31 extends straight from one end of the reflector 2 to the other end point. In other words, the conductive pattern 31 is formed along the shortest path in the direction of the longitudinal axis of the reflector 2. As described above, the reflector 2 is formed of an insulating material, and accordingly, any leakage current flows out of the conductive pattern 31 through the reflector 2. The conductive pattern 31 may be a screen printed on the vertical flat portion 2a of the reflector 2. The conductive pattern 31 is formed of a heat-setting resin and has a thickness falling on the order of 0.03 mm. The heat-setting resin is elastic, and it is less likely to cause cracks in the conductive pattern 31 due to the advantage of being extremely elastic. Further, the conductive pattern 31 is quite thick. Although the thickness of the conductive pattern 31 may be thicker than the conventional conductive pattern 36 whose thickness falls within the range of 0.0005 mm to 〇·1 mm, the thickness of the conductive pattern 31 may fall from 0.5. MM to 1.0 mm -10- 1 260 260 V. Inventive Note (9) The round cable 32 in the enclosure will be more flexible than the elastic flat cable/viscous compound layer 3 3/34 with a thickness of 0.2 mm and 0.1 mm. thin. The extremely thick thickness makes the conductive pattern 31 intocapable of withstanding thermal stress, and the disconnection phenomenon is less likely to occur. The heat setting resin is formed of a conductive enamel layer which is screen printed on the vertical flat plate portion 2a. The conductive crucible can be corrected by a copolymerized polyester mixed with silver (Ag) and carbon (C). The heat setting resin is extremely viscous to the polyethylene terephthalate resin and has great elasticity. Because of this reason, even if thermal stress is applied to the reflector 2, the conductive pattern 31 is hardly peeled off from the reflector 2. The lamp tube 1 has a cylindrical shape and has a pair of electrodes 1 1 /1 2 formed on the end surface of the tube 1 ◦. The electrode 11 is formed on one end surface of the bulb 1 to apply a high voltage to the electrode 11.

The liquid crystal display device also includes a liquid crystal panel 5 and a circuit board 6. The drive circuit is combined on the circuit board 6. The circuit board 6 is provided along the side line of the liquid crystal panel 5 and is attached to the liquid crystal panel 5. The optical guide plate 4 is superposed on the liquid crystal panel 5 and the circuit board 6. If so, the liquid crystal panel 5, the circuit board 6, and the light source 1 are assembled and housed in the casing 40. When the lamp 1 启动 is activated, light is emitted from the lamp 1 到 to the optical guide -11 1 1288260 5, the invention (10) guide 4, and part of the light is reflected on the inner surface of the reflector 2 . At the same time, the reflected light is incident on the side surface of the optical guide plate 4. Light is transmitted through the optical guide plate 4 and is output from the upper surface of the optical guide plate 4. If so, the liquid crystal panel 5 is exposed to light. The driving circuit supplies the image bearing signal and the scanning signal to the data electrodes and the scanning electrodes of the liquid crystal panel 5, and locally changes the transparency of the liquid crystal. As a result, light passes through the transparent portion of the liquid crystal panel 5, and an image is generated on the liquid crystal panel 5. While the driving circuit generates an image on the liquid crystal panel 5, not only light but also heat is radiated toward the reflector 2, and the heat energy increases the temperature of the reflector 2. This thermal energy is causally related to the thermal stress system. However, the conductive pattern 31 is thick enough to withstand its thermal stress. For this reason, it is not easy to cause disconnection and cracking in the conductive pattern 31. The image is generated on the image generation area of the liquid crystal panel 5. The liquid crystal panel 5 is exposed on the central area of the outer casing 40. However, the peripheral area of the outer casing 40 cannot be used for image generation. As described above, a low voltage is applied to the electrode 12 of the bulb 10 through the conductive pattern 31, and the conductive pattern 31 has a thickness falling on the level of 0.03 mm. This means that the manufacturing of the outer casing 40 is designed such that the side plates 40 a are close to the reflector 2. The outer casing 40 is lightweight. However, it has not reduced the area of its imagery cattle. Thus, the light source 1 according to the present invention is electrically conductive with a lightweight liquid crystal display device without sacrificing its image generation area. Process -12- 1288260 V. Description of Invention (u) First, a method for manufacturing the reflector 2 will be described. The method is used in this method. The Hai manufacturing system is decomposed into: extrusion molding machine 4; printing machine 50; cutting machine 5 5; thermoplastic device (not shown). The extrusion molding machine 40' generates a passage bar 59 from the raw material, and forms a conductive pattern 31 on the passage bar 59 by means of a printer 5. The passage bar 59 is cut into a plurality of short passage bars 2a by a cutter 55, and the reflector 2 is obtained through a thermoplastic device (not shown). The extrusion molding 401 comprises: a heating cylinder μ; a feeding funnel 42; a spiral (not shown); an electric motor 43; a mold nozzle 44; a forming die 45; a cooling tank 46° feeding funnel 42 attached to the heating cylinder 4 The crucible is placed and the raw material is supplied into the inner space of the heating cylinder 41 through the feed funnel 42. The raw meal is heated and softened. A spiral (not shown) is provided in the internal space and is rotated by the drive of the electric motor 43. The ergonomic material is extruded through the die nozzle 44 and the push bar 6 〇. The rod 60 is molded into the passage bar 59 by forming the mold 45, and is cooled in the cooling groove 46 to solidify the passage bar 59. If so, the via bar 5 9 is output from the cooling bath 46. The printer '50 is comprised of a dispenser 5'. The conductive crucible 3 ! a is supplied through the guide 5 2 to the dispenser 5 , and the conductive crucible 3 ] a is printed onto the vertical flat portion of the via bar 59. The cutter 5 5 includes a drive roller 56 and a cutter blade 57. The drive roller 56 moves the access rod 59 toward the cutter 5 5 and cuts the passage bar 5 9 into a plurality of short passage bars 2a by a cutter blade 57. The short-pass bar 2a is transported to a thermoplastic device (not shown) and the conductive layer is placed in the thermoplastic device (not labeled). 13- 1288260 5. The printed layer of the invention (12) Bake. If so, the reflector 2 having the conductive pattern is continuously manufactured. In the method described above, the conductive crucible is printed onto the vertical flat portion of the via bar 59 after the cooling step. However, it is also possible for us to print the conductive crucible onto the vertical flat portion of the rod 60 prior to the cooling step as shown in Figure 11. The access rod 59 is very hot. When the conductive crucible is printed onto the rod 60, the electrically conductive crucible is partially cured by the exchange of thermal energy between the thermal rod 60 and the electrically conductive crucible. This will result in enhanced adhesion between the reflector 2 and the conductive pattern 31. As will be understood from the foregoing description, the conductive crucible is printed on the reflector 2 and the electrically conductive crucible layer is subjected to a thermal baking action. This printing technique is suitable for giving a conductive pattern 31 having a suitable thickness. The reflector 2 having the conductive pattern 31 is produced by the method as described above. This printing technique does not require a long time and is more economical than evaporation. The production has been improved and the manufacturing costs have been reduced to a certain extent. In addition, a via bar 59 having a conductive layer of tantalum is continuously produced at a very high rate through the manufacturing system. Its production has been improved and its manufacturing costs have been significantly reduced. The 'last' conductive paste is printed by using the dispenser 51. The distributor 51 will shape the conductive crucible into a strip on the access rod 59. For this reason, an arbitrary mask is required to perform the printing phase. SECOND EMBODIMENT Turning now to Fig. 2, another reflector 2c for illustrating the present invention is formed in the form of a groove elongated in the longitudinal direction. The 14- 1288260 V. Description of the Invention (3) The groove is formed in the vertical flat plate portion 2a of the reflector 2c and has a depth falling on the level of 0.03 mm. The conductive coating is printed on the bottom surface of the groove and cured by thermoplastic action. The conductive pattern 3 1 is completely embedded in the vertical flat plate portion 2a of the reflector 2c, and has a surface having the surface of the vertical flat plate portion 2a in a two-dimensional plane. With the reflector 2c, it is possible to further make the liquid crystal display device lighter. The groove can be formed therein by forming a mold. As will be understood from the foregoing description, the printed pattern 31 is printed on the reflector 2, and the printing technique gives a conductive pattern 31 having a suitable thickness. Although the thermal stress is applied to the printed pattern 31, the printed pattern 31 can withstand its thermal stress without causing detachment and cracking. The reflector 2c and the conductive pattern 31 are formed of a conductive heat-setting resin and an insulating thermoplastic resin, respectively, and the conductive heat-setting resin exhibits a good adhesion to the insulating thermoplastic resin. In addition, the conductive heat setting resin is elastic. For this reason, it is difficult to separate the conductive pattern 31 from the reflector 2c. If so, the conductive pattern 31 is not peeled off. It is expected that the conductive pattern 31 can achieve a great resistance to thermal stress and a narrow footprint. From this point of view, the thickness of the conductive pattern falls within a certain range. The good adhesion between the thin conductive pattern 31 and the reflector 2c is formed by the heat setting resin and the thermoplastic resin in the above embodiment. We can also use other combinations of materials. Having described and illustrated a particular embodiment of the invention, it will be apparent to those skilled in the art of <RTIgt; </RTI> <RTIgt; Make various changes and corrections. A plurality of conductive patterns 3 1 b, i.e., a plurality of conductive strips, are formed on the vertical flat plate portion 2a in a mutually parallel manner as shown in Fig. 13. In this case, even if an understanding occurs in one of the plurality of conductive strips, the other conductive strips can cause a low voltage to propagate from the low voltage line 3b to the electrode 12. If so, the plurality of conductive patterns enhance the reliability of the interconnect structure 36. The conductive cymbal can be formed on the vertical flat plate portion 2a through the mask by using a compressible technique in screen printing. The reflector according to the invention can be used in another optical device such as a lighting device.
